Genetic defects in PCNT, encoding the centrosomal protein pericentrin, cause a rare syndrome of primordial dwarfism, skeletal dysplasia and facial dysmorphism, known as Majewski Osteodysplastic Primordial Dwarfism Type II (MOPDII). We now report that 11 out of 15 patients with PCNT defects had clinical and/or biochemical evidence of severe insulin resistance (IR), many also with severe dyslipidaemia; the remaining four were under 4 years-old. The metabolic profil...

GH-secreting pituitary adenomas are by far the commonest cause of acromegalic soft tissue overgrowth. However the differential diagnosis includes pseudoacromegaly in rare patients with severe insulin resistance, with or without lipodystrophy, and some congenital overgrowth syndromes such as Sotos’ syndrome, due to mutations in the NSD1 gene. We now report the case of two siblings, born to non consanguinous, clinically unaffected Europid parents, with childhood over...
